Step-by-step explanation:
Sharonda is plotting quadrilateral PQRS on the graph below She will plot the fourth and final vertex, S, at (9, 5), the length of side PS will be 11 units.
What is quadrilateral?A quadrilateral is a four-sided polygon. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. There are several types of quadrilaterals, including: Square, rectangle, parallelogram, rhombus, trapezoid, and kite.
Length of side PS can be calculated using the distance formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Where,
P(-2, 5) = ([tex]x_1,y_1[/tex]) (the coordinate of P is gotten from the graph).
Given that,
S(9, 5) = ([tex]x_2,y_2[/tex])
PS = [tex]\sqrt{(9-(-2))^2+(5-5)^2}[/tex]
PS = [tex]\sqrt{11^2+0^2}[/tex]
PS = [tex]\sqrt{121}[/tex]
PS = 11units.
Thus, the answer is 11 units.

How can you use the properties of operations to evaluate this expression? 18 + 4(28)
You can use the commutative property to rearrange the problem like this, 18 + 28 * 28 * 28 * 28 = 130
Basically, you can use the properties of operations to solve 18 + 4(28) in various ways. Though whichever operation you apply must give you the same result. The result of 18 + 4(28) is 130.
Step-by-step explanation:The four basic types of properties of operations are commutative, associative, distributive and identity. These properties only apply to the operations of addition and multiplication.
According to the purplemath site, "The word 'commutative' comes from 'commute' or 'move around', so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is 'a + b = b + a'; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is 'ab = ba'; in numbers, this means 2×3 = 3×2."
According to the splashlearn site, "the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are grouped. Here's an example of how the sum does NOT change irrespective of how the addends are grouped. Here's another example. ( 75 + 81 ) + 34."
According to the mathwarehouse site, "In general, this term refers to the distributive property of multiplication which states that the. Definition: The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."
According to the math site, "Identity property. The identity property for addition tells us that zero added to any number is the number itself. Zero is called the 'additive identity.' The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself."
Answer:
Sample response: Use the distributive property and expand 28, then distribute the 4 to 20 and the 4 to 8. Then you have 18 + 80 + 32. Use commutative property to reverse the order of 32 and 80 so that 18 and 32 are friendly numbers to add.
Step-by-step explanationWhich reasons did you include in your response? Check all that apply.
The distributive property can be applied to multiply 4(28) mentally.
The number 28 can be expanded to 20 + 8.
The commutative property can be applied to reverse the order of numbers.:

Taylor has 18 cents in dimes and nickels in her pocket. The number of dimes is four more than the number of nickels. How many of each coin does it have?
Answer:
Explained below.
Step-by-step explanation:
The value of different types of coins are as follows:
1 penny (p) = 1 cent
1 nickel (n) = 5 cents
1 dime (d) = 10 cents
1 quarter (q) = 25 cents
It is provided that Taylor has 18 cents in dimes and nickels in her pocket.
This is not possible.
Because the sum of any number of dime and nickel coins will always be a multiple of 5.
a·d + b·n = 10a + 5b = 5 (2a + b)
The value 18 cents can be formed as follows:
8p + d = 18 cents
3p + n + d = 18 cents
3n + 3p = 18 cents

........Median vs mean?
The mean is affected by the skewness, whereas the median is not.
==================================
Let's go through the answer choices to see which are true and which are false.
A. True. The mean takes account of all the values since we sum all the values and divide by the number of values. The median only looks at the middle most value. The median does not take into account any other value. So the outliers can move wherever you want and the median will not be affected.B. False. It depends on what the context of the situation is. Both measures of center have their strengths and weaknesses. The median is only preferred if there are outliers. That way we get a sense of where the center is and know that the center isn't being pulled on by the outliers. A good example is home real estate as this problem mentions.C. False. The mean is larger than the median if the data is skewed right. Skewed right data means we have a large outlier(s) to the right side pulling the mean toward that location. An example would be having homes in some range of say 50 to 100 thousand, and then an outlier mansion would have a price of 20 million dollars. This skews the mean to be larger than it should be (when it should be somewhere between 50 and 100 thousand). Note: sometimes a trimmed mean is used instead of the medianD. False. The mean should only be used if we don't have any outliers at all. In other words, the mean should only be used if the data is not skewed left and not skewed right either. E. False. This computes the midrange and not the median. In my experience with many stats problems, the midrange doesn't really come up that often. Though I could just have a limited viewpoint of course.Given that 1 inch = 2.54 cm, how many centimeters are there in 8 feet? Answers may be written using decimal form and should be rounded to the nearest hundredth when necessary.
Answer:
There is 243.84 cm in 8 feet.
Step-by-step explanation:
We have:
1 inch = 2.54 cm
1 feet = 12 inch
We can find the number of centimeters (n) present in 8 feet as follows:
[tex] n = \frac{2.54 cm}{1 inch}*\frac{12 inch}{1 ft}*8 ft = 243.84 cm [/tex]
Therefore, there is 243.84 cm in 8 feet.

If -2(3y+5)= -4, find the value of 5y.
Answer:
5y = -5
Step-by-step explanation:
-2(3y+5)= -4
Divide each side by -2
-2/ -2 (3y+5)= -4/-2
3y+5 = 2
Subtract 5 from each side
3y +5 -5 = 2-5
3y = -3
Divide by 3
3y/3 = -3/3
y = -1
5y = 5*-1 = -5
The sum of $224 was divided among 3 people so that the second person received $1 less than twice as much as the first, and the third received $11 more than second. How much did each person receive? 1st person: 2nd person: 3rd person: show work
Answer:
1st person: $432nd person: $853rd person: $96Step-by-step explanation:
Let a, b, c represent the amounts received by the first, second, and third person, respectively.
2a-1 = b
c = b+11
a + b + c = 224
Substituting for c, we have ...
a + b + b+11 = 224
a +2b = 213
Substituting for b, we have ...
a +2(2a -1) = 213
a +4a -2 = 213 . . . . . eliminate parentheses
5a = 215 . . . . . . . . . . add 2
a = 43 . . . . . . . . . . . . .divide by 5
b = 2a -1 = 2(43) -1 = 85
c = b +11 = 85 +11 = 96

The length is one more than three times the width.
Find the dimensions of the garden.
Answer:
length = 217 ydwidth = 72 ydStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 578 yds
The statement
The length is one more than three times the width is written as
l = 1 + 3w
Substitute the expression into the above formula and solve for the width
That's
578 = 2(1 + 3w) + 2w
578 = 2 + 6w + 2w
8w = 576
Divide both sides by 8
w = 72
Substitute w = 72 into l = 1 + 3w
That's
l = 1 + 3(72)
l = 216 + 1
l = 217
Therefore the dimensions are
length = 217 yd
width = 72 yd

m[n(x)] = n[m(x)] = x
Here, m(x) = [tex]\frac{3x}{x+7}[/tex] and n(x) = [tex]\frac{7x}{3-x}[/tex]
m[n(x)] = [tex]\frac{3(\frac{7x}{3-x})}{(\frac{7x}{3-x})+7}[/tex]
= [tex]\frac{21x}{7x+21-7x}[/tex]
= x
n[m(x)] = [tex]\frac{7(\frac{3x}{x+7})}{3-\frac{3x}{x+7}}[/tex]
= [tex]\frac{21x}{3x+21-3x}[/tex]
